As a further bit of info, the UA-important level is defined in the Cascade module at <http://dev.w3.org/csswg/css3-cascade/#cascade>. It's higher than everything except Transitions (and maybe Animations, depending on the browser right now, but that'll settle down soonish). This means that it's impossible for author-level code to override the property, but I think that's what the correct and desirable behavior is for this. ~TJ
